Description

Technical Field

[0002] Inductor components are one of the three major components in the electronic component industry, and they play an extremely important role in the electronics industry. In the production process of small inductor terminals, they need to be accurately inserted into the powder forming mold before being pressed and formed. However, the small inductor terminals are tiny in size and difficult to load. Traditional small terminal loading also has many disadvantages. For example, the manual swinging method for U-shaped small terminals is not only inefficient, but also cannot guarantee the pin spacing of each terminal. The terminals are prone to tilt, resulting in a high misalignment rate of the formed terminals, and the consistency and quality of the finished products cannot be guaranteed. In addition, in the vibration plate of the traditional feeder, the U-shaped small terminals are prone to jamming or overlapping due to different opening directions or bending angles. In addition, the traditional terminal feeder cannot be linked with the powder forming press, has a low degree of automation, and requires manual handling of jigs, which is time-consuming and labor-intensive, making it difficult to achieve mass production.

The picking and unloading robot 6 can drive the positioning jig 2 on the feed transfer mechanism 5 to transfer to the pressing part of the external powder molding press and push out each U-shaped small terminal of the inductor in the positioning jig 2 to realize material removal.

[0032] In this embodiment, the positioning fixture 2 may be provided with a plurality of clamping holes 21 which are arranged through and used to clamp the U-shaped small terminal of the inductor. The U-shaped small terminal of the inductor is positioned through the clamping holes 21 to ensure that the pin direction and spacing thereof meet the mold requirements.

[0033] Specifically, if Figure 3 and Figure 4As shown in the figure, the positioning fixture 2 may include a fixture top plate 22, a fixture end cap 23, positioning inserts 24, abutting blocks 25, and abutting springs 26.

[0034] Among them, the positioning fixture 2 realizes the high-precision positioning of the inductor U-shaped small terminals by using the elastic clamping hole channel 21 jointly composed of the abutting blocks 25, the abutting springs 26, and the abutting guiding pieces 242, avoids the deviation of traditional manual material placement, and reduces the terminal misalignment rate after forming.

[0039] In this embodiment, the material distribution mechanism 4 receives the inductance U-shaped small terminals from the feeding mechanism 3. The profiling chute 431 keeps the pin directions of all the inductance U-shaped small terminals consistent. The inductance U-shaped small terminals are separated one by one through the material pushing device 45 and accurately inserted into the clamping hole channels 21 of the positioning jig 2 to ensure consistent spacing, improving the separation and insertion accuracy of the inductance U-shaped small terminals.

Among them, the fixture carrying mechanism 7 can drive the pick-and-place manipulator 6 to move up, down, left, and right, and further drive the precise transportation of the positioning fixture 2.

[0043] As Figure 10 shown, preferably, the pick-and-place manipulator 6 may include a pick-and-place mounting vertical plate 61, a pick-and-place connecting plate 62, a lifting slide table 63, a pick-and-place support arm 64, and a stripping device 65.

One side of the stripping fixed seat 652 is fixedly connected to the bottom surface of the other end of the pick-and-place arm 64.

There are several groups of stripping ejector pins 653, which respectively correspond to each clamping hole 21 and their tops are respectively spaced and connected to the bottom surface of the stripping top plate 651. The stripping movable seat 656 is movably inserted into the bottom groove of the stripping fixed seat 652, and its top two sides are slidably connected to the sliding holes 6521 formed through the front and back of the stripping fixed seat 652 through the air pipe body 654. The bottom of each stripping ejector pin 653 sequentially passes through the stripping fixed seat 652 and the stripping movable seat 656. There are two fixture suction cups 655, both of which are embedded downward at the bottom of the stripping movable seat 656. There are two spring limit posts 658, which are respectively embedded upward in the stripping movable seat 656 and their tops extend into the first spring accommodation holes 6561 formed on both sides of the top of the stripping movable seat 656. The return springs 657 are respectively sleeved on the ends of the spring limit posts 658 and are movably arranged in the first spring accommodation holes 6561 and the second spring accommodation holes 6522 correspondingly formed in the upper part of the stripping fixed seat 652. Each stripping ejector pin 653 can pass through the bottom surface of the stripping movable seat 656 when the stripping movable seat 656 compresses the return spring 657 upward and is located inside the stripping fixed seat 652.

[0046] Among them, the stripping device 65 of the pick-and-place manipulator 6 can push the inductive U-shaped small terminals in the positioning fixture 2 downward into the pressing part of the powder molding press through structures such as the stripping ejector pins 653 and the return spring 657 to achieve stripping. At the same time, the pick-and-place manipulator 6 can also drive the empty positioning fixture 2 to return to the material plate rack 53 of the initial feeding transfer mechanism 5, realizing continuous feeding and improving the automation degree and production efficiency of production.

[0047] As Figure 12 shown in the figure, it may further include a CCD detection camera device 8 for detecting whether each positioning fixture 2 is filled with inductive U-shaped small terminals. The CCD camera detection device 8 is fixedly installed on the back of the gantry 11.

The light source 84 is installed on one side of the bottom of the camera mounting frame 81 through the light source fixing block 85 and is located directly below the CCD camera 82.

[0048] Among them, the CCD detection camera device 8 can detect whether each positioning fixture 2 is filled with inductive U-shaped small terminals, which is used to monitor the feeding state in real time, avoid problems such as missing materials and misfeeding, improve the yield rate, has a high degree of automation, and reduces the manual detection cost.

[0049] The working principle of this embodiment is as follows:

[0050] First, the positioning fixture 2 on the pallet rack 53 of the feeding transfer mechanism 5 is in an empty state. The inductive U-shaped small terminals are fed through the vibrating disk 31 and the feeding track 33. The profiling chute 431 of the vibrating disk static track 43 of the material distribution mechanism 4 ensures that the pin directions of the inductive U-shaped small terminals conveyed by the feeding track 33 are consistent. The ejector cylinder 451 drives the terminal ejector pin 452 to move downward, and the inductive U-shaped small terminals are inserted one by one onto the wedge-shaped convex body 253 in each clamping hole 21 of the positioning fixture 2 through the ejector hole 432. Under the action of the abutting spring 26, the abutting block 25 and the abutting guide piece 242 can clamp the inductive U-shaped small terminals.

[0051] Next, the Y-axis linear module 51 and the X-axis linear module 52 drive the positioning fixture 2 on the pallet rack 53 to move below the CCD detection camera device 8. The CCD camera 82 detects whether the small terminals in the positioning fixture 2 are full. After the detection is completed, it drives the positioning fixture 2 to move below the fixture carrying mechanism 7. The first translation linear module 71, the Z-axis linear module 72, and the second translation linear module 722 cooperate to drive the pick-and-place manipulator 6 to move to the grasping station, and the pick-and-place manipulator 6 sucks the positioning fixture 2 through the fixture suction cup 655 and transfers it above the pressing part of the powder molding press. After reaching above the press, the pick-and-place manipulator 6 moves downward until the stripping movable seat 656 compresses the return spring 657 upward, and the stripping ejector pin 653 penetrates from the bottom of the stripping movable seat 656, and each inductive U-shaped small terminal is pushed into the press die cavity together.
